My invention relates to improvements in supporting plates for the oscillatory 'jeoire used in connection with oil Well pumps, the object of the invention being to provide en extremely simple and inexpensive device o2 this olisreoter Whioli rosy be adjusted loori Zontelly on e pivotal stri? for tlie purpose of properly dining the jaolr "with the other equipment, with which it (Jo-operates,

' "With the foregoing in view, the invention resides in the novel subject nietter herein.

after described and olsirned, description being supplemented by the eeeornpenying drawing.

Figure l is o, side elevation oi my invention and e. portion oi e jeol thereon.

Figure 2 is e top plan view.

ln the drawing eoove brieilvdeseribed, the numeral l designates e portion of Well lnoivn oil Well jack having the usual transverse horizonte?. tulornin 2. l provide en elongated eed plate 3 support tliis tule Crum, the upper surface oi tlie plete being provided with e groove l extending; enlisted tizilljyv throughout its length to receive the iulorurn,tlie ends ot tlie groove being Closed by upstending lugs 5 ivliioli prevent endivis movement of seid nlornm it one side the groot/e fl, the upper side or the bed p me 3 is provided with e pair oiP4 lioolrs 8 to engege the iulernni 2 Wliile guard ribs 7 may well lie formed et the other side oi seid groove. Also, tlie upper surface or" the lived plete may be tliiolrened Whereverdesired for reinforcing purposes, as indicated on die draivinv. One of these tliieliened portions, designated liv the reference oliersoter 8, is formed with e slot 9 parallel with the groove t and disposed bet-Ween this groove and one plete 3 are provided gli, toward one end to rnent of pair oi nenor rods le vvliioli poss therethrough. ends or tliese rodsj reorn tlie letYJ 3 ere provided with anchors lo vvliieli preferably oi lfsnepe, to lioolr. over one of the foundation ll, tlie upright erins of seid enoliors having openings through which the enonor rods le pass. The numerals lo designate Washers Wliioli are thinned to-Werd one edge and interposed lo tween the nuts l? of the rods le and the logs l2.. Before tightening of the nirtsv tlie Westers may `oe set so that they will Contact -both with tlie lugs and the nuts', giving n loe-tiring surface, regerdless of the ongle to which the rods lll are swung vvitli respeot to the leed plete.

By the use of the invent-ion, it will lie seen that eiter bolting the bed plete B to the ionndstion by ineens oi tlie bolt l0, the rods le inev loe adjusted so that tlie jeolr may be propeilv positioned to operate rnost iid-van togeouslv. The bolt l0 end tire nuts 17 may tiren lie linelly tightened to seeurelv loolr the device in place.

The lied plete is oi" entreinely simple and inexpensive constroo-tion9 yet it will te highly elioient end in overt7 ivov desirable. As excellent results nio-y lie obtained from the details disclosed, they ere preferably iol-r lovved. However, within the soope of the invention es elenned, numerous minor changes may loe inode.

l oleirn:

l. li devies of' the oliereoter described comprising e bed plete edepted to pivotellv support e j'aolr, e pivot lietvreen tlie ends of seid plete for connecting the letter with e foundation to permit horizontal swinging thereof7 the ends of said plate being provided with projecting lugs havingv tapered openings formed horizontally therethrough, and e pair of anchor rodsV received in seid openings, seid rods having anchors to engege the foundation.

2. A structure as speciied in claim l; said anchors being of Lsheped forni to hook around one edge of the foundation and hevng openings in their upright arms receiving said rods.

In testimony whereof have hereunto axed my signature.
